Title: Puffer type gas-blast circuit breaker
Inventor: KONO HIROMICHI
IPC: H01H33/82
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To provide a puffer type gas-blast circuit breaker which prevents pressure within an arc extinguishing chamber from being lowered caused when small current is cut off, and thereby exhibits excellent breaking performance. SOLUTION: Arc current shunted at a current flow passage 19 forces a coil part 31 to produced a magnetic field, and by the action with the magnetic field, a metallic cylinder 20 is subjected to electromagnetic force. The electromagnetic force is proportional to the intensity of arc current, and when arc current is small, no metallic cylinder 20 is moved because the electromagnetic force can not overcome the force of a spring 21. Therefore, arc extinguishing gas is exhausted out of an exhaust port 26 provided for the current flow passage 19, and the pressure of a puffer chamber 18 is prevented from being increased.  On the other hand, when arc current is high in amperage, the electromagnetic force overcomes the force of the spring 21, the metallic cylinder 20 is moved so as to allow the exhaust port 26 provided for the passage 19 to be blocked, the pressure of the puffer chamber 18 is increased, and excellent breaking performance can thereby be exhibited even when heavy current is shut off.

Title: Audio signal reproducing device equipped with noise eliminating circuit
Inventor: WATAYA DENJIYUN
IPC: H04N5/93
Filed: 1980-08-25
Abstract: PURPOSE:To reduce noises by shortening a previous-value holding time, by changing a switching circuit over to a side where neither an LPF nor a previous-value holding circuit resides in a period except when the previous value of a dropout  period including a transient period due to the LPF is held. CONSTITUTION:An audio FM signal passed through a BPF2 is detected by a dropout detecting circuit 7 and at the ending of the dropout detection signal, a monostable multivibrator 16 is triggered, thereby outputting a pulse with pulse width equivalent to the transient periof of a signal delay circuit 14. Then, a previous-value holding circuit 6 is put in operation by operating an OR circuit 9, and a switching circuit 15 is changed over to a circuit 6 side. Consequently, the switching circuit is connected to the side of the previous-value holding dircuit 6 where an LPF6 is connected only during the dropout period of the audio FM signal and the short transient period of the output of the circuit 14 due to the BPF2, so a previous-value holding time is shortened to reduce noises of the audio FM signal due to dropouts.
